Yes. Take the functions
f(x) = log(x)
or
g(x) = ln(x)
In both cases, there is a vertical asymptote where x = 0. Because a number cannot be taken to any power so that it equals zero, and can only come closer and closer to zero without actually reaching it, there is an asymptote where it would equal zero. Note that transformations (especially shifting the function left and right) can change the properties of this asymptote.

Asymptotes are one way - not the only way, but one of several - to analyze the general behavior of a function.

Exponential and logarithmic functions are different in so far as each is interchangeable with the other depending on how the numbers in a problem are expressed. It is simple to translate exponential equations into logarithmic functions with the aid of certain principles.
They are inverses of each other.
